Description

Technical Field

[0001] This utility model relates to the field of chamfering technology for welding and cutting, and more specifically, to a chamfering head and an intelligent chamfering device. Background Technology

[0002] In the welding and cutting process, especially in the welding and cutting production line, in order to improve the cutting quality of the workpiece, it is necessary to perform chamfering on the edges of the cut workpiece to improve the flatness of the edges of the cut workpiece and meet the needs of subsequent processing technology.

[0003] Although manual chamfering has been gradually replaced by automated chamfering equipment, during the chamfering process, due to positioning errors and other reasons, the chamfering cutter may not align with the workpiece edge when the chamfering head approaches the workpiece. This can cause a collision between the chamfering cutter and the workpiece, and this rigid collision can also be transmitted to the actuators such as the robotic arm or gantry connected to the chamfering head, causing damage to these actuators as well. This makes automated chamfering equipment unable to effectively achieve unattended operation and unable to adaptively respond to unexpected situations. Utility Model Content

[0036] The technical effects of this utility model include at least the following:

[0037] This invention utilizes the spherical structure of a spherical bearing mechanism to allow the electric spindle to swing in any direction while simultaneously moving up and down relative to the spherical bearing mechanism. This allows the chamfering tool at the bottom of the electric spindle to swing and move up and down when impacted or unable to effectively align with the workpiece surface, preventing both the electric spindle and the chamfering tool from being simultaneously squeezed by the workpiece and the actuator. Furthermore, during the spindle's movement, a spring-loaded reset mechanism provides cushioning and protection. After the spindle slides up and down and / or swings in any direction, the spring-loaded reset mechanism returns the spindle to a set position, typically its original position, which is also the working position of the chamfering tool.

[0038] In addition, during normal operation of the chamfering machine head, a spring-loaded reset mechanism works in conjunction with the electric spindle to keep the electric spindle in a set position, which is also the working position of the chamfering cutter. This prevents the chamfering cutter from wobbling during normal use, thus ensuring that the electric spindle can continuously drive the chamfering cutter to perform chamfering operations.

[0039] Thus, through the coordinated operation of the base, chamfering cutter, spherical bearing mechanism, and elastic reset mechanism in this invention, the chamfering operation is automated. Simultaneously, it improves the adaptability of the chamfering head during contact with the workpiece, preventing damage to the electric spindle, chamfering cutter, and actuator caused by collisions between the electric spindle or chamfering cutter and the inclined workpiece. This enables the automatic chamfering equipment to effectively achieve unattended operation and adaptively respond to unexpected situations. Attached Figure Description

[0054] See Figures 1 to 7 This embodiment provides a chamfering head, including:

[0055] Base 1;

[0056] The chamfering cutter 2 is disposed below the base 1;

[0057] An electric spindle 3 is provided, and the chamfering tool 2 is detachably connected to the bottom end of the electric spindle 3. The electric spindle 3 is used to drive the chamfering tool 2 to rotate.

[0058] A spherical bearing mechanism 4 is connected to the side of the base 1. The electric spindle 3 is vertically inserted into the spherical bearing mechanism 4. The electric spindle 3 slides up and down along the spherical bearing mechanism 4. The spherical bearing mechanism 4 is used to allow the electric spindle 3 to swing in any direction.

[0059] A spring-loaded reset mechanism 5 is disposed at the electric spindle 3. The spring-loaded reset mechanism 5 cooperates with the electric spindle 3. The spring-loaded reset mechanism 5 is used to keep the electric spindle 3 in a set position, and after the electric spindle slides up and down and / or swings in any direction, it resets the electric spindle 3 to the set position.

[0060] It should be noted that the electric spindle 3 sliding up and down and / or swinging in any direction here includes the composite motion of the electric spindle 3 sliding up and down while swinging in a certain direction, as well as the electric spindle 3 sliding up and down or swinging in any direction.

[0061] Additionally, it should be noted that the base 1 can be connected to the actuator of an automatic chamfering device, such as a robotic arm or the lifting head of a mobile gantry, to achieve chamfering operations on the workpiece.

[0062] In addition, the chamfering tool 2 in this embodiment can be mounted under the BT30 tool holder, and the BT30 tool holder can be detachably connected to the electric spindle 3.

[0063] This embodiment utilizes the spherical structure of the spherical bearing mechanism 4 to allow the electric spindle 3 to swing in any direction. Simultaneously, the electric spindle 3 can move up and down relative to the spherical bearing mechanism 4. This allows the chamfering tool 2 at the bottom of the electric spindle 3 to swing and move up and down when impacted or unable to effectively align with the workpiece surface, preventing both the electric spindle 3 and the chamfering tool 2 from being simultaneously squeezed by the workpiece and the actuator. Furthermore, during the movement of the electric spindle 3, the elastic reset mechanism 5 provides buffer protection. After the electric spindle 3 slides up and down and / or swings in any direction, the elastic reset mechanism 5 returns the electric spindle 3 to a set position, typically its original position, which is also the working position of the chamfering tool 2.

[0064] In addition, during normal operation of the chamfering machine head, the elastic reset mechanism 5 cooperates with the electric spindle 3 to keep the electric spindle 3 in a set position, which is the working position of the chamfering cutter 2. This prevents the chamfering cutter 2 from wobbling during normal use, thereby ensuring that the electric spindle 3 can drive the chamfering cutter 2 to continuously perform chamfering operations.

[0065] Thus, through the coordinated operation of the base 1, chamfering cutter 2, spherical bearing mechanism 4, and elastic reset mechanism 5 in this embodiment, the chamfering operation is automated. Simultaneously, it improves the adaptability during the contact process between the chamfering head and the workpiece, preventing damage to the electric spindle 3, chamfering cutter 2, and actuator caused by collisions between the electric spindle 3 or chamfering cutter 2 and the inclined workpiece. This enables the automatic chamfering equipment to effectively achieve unattended operation and adaptively respond to unexpected situations.

[0073] Multiple upper push springs 514 are fitted one-to-one around the guide post 513. Each upper push spring 514 is positioned between the baffle 512 and the bearing seat 41, and is used to push the baffle 512 upwards.

[0074] Multiple compression springs 515 are fitted around the guide post 513 in a corresponding manner. The compression springs 515 are placed between the baffle 512 and the limiting mechanism 516. The compression springs 515 are used to press the baffle 512 downward, and the limiting mechanism 516 is used to restrict the compression springs 515 from moving upward.

[0075] Multiple guide posts 513 are used to guide the movement, and multiple upper springs 514 and multiple lower springs 515 are used to buffer and reset the movement, so that the electric spindle 3 can be reset to a set height after sliding up and down.

The bottom end of the guide post 513 is fixed by each bolt 5135 passing through a first threaded through hole and threadedly connected to a second threaded through hole.

[0085] See Figures 1 to 7 Furthermore, the elastic reset mechanism 5 also includes:

[0086] A radial reset mechanism 52 is provided at the base 1. The radial reset mechanism 52 is used to keep the electric spindle 3 at a set position and to reset the electric spindle 3 to the set position after the electric spindle swings in any direction.

[0088] A circular base 521 is connected to the base 1, and the circular base 521 is disposed below the joint bearing mechanism 4. The bottom of the electric spindle 3 is inserted into the circular base 521; and

[0090] See Figures 1 to 7 Furthermore, the elastic pushing mechanism 522 includes:

[0091] The radial sleeve 5221 is detachably connected to the annular base 521;

[0092] The push rod 5222 has a limiting flange 5225 near its front end. The push rod 5222 is inserted into the radial sleeve 5221. The front end of the push rod 5222 extends out of the front end of the radial sleeve 5221 and contacts the electric spindle 3.

[0099] The electric spindle 3, the joint bearing mechanism 4, and the elastic reset mechanism 5 are enclosed by a housing, which protects and prevents dust from entering the electric spindle 3, the joint bearing mechanism 4, and the elastic reset mechanism 5.

[0100] In addition, this embodiment provides an intelligent chamfering device, including the chamfering head and the actuator, wherein the actuator is a robotic arm or a gantry, and the base 1 of the chamfering head is connected to the actuator.

[0101] Since the intelligent chamfering device achieves the same technical effect as the chamfering machine head, the intelligent chamfering device will not be explained further.

[0102] See Figures 1 to 7 Furthermore, the intelligent chamfering device also includes a visual inspection device, which is located at the actuator.

[0103] By using a visual inspection device in conjunction with the chamfering machine head, automatic positioning and inspection can be achieved during the chamfering process.

[0104] Preferably, the chamfering cutter 2 is a forming cutter. When the robotic arm moves the chamfering cutter close to and attaches it to the steel plate, the chamfering cutter is kept upright and the blade of the chamfering cutter is aligned with the edge of the steel plate.

[0105] Preferably, the chamfering tool includes a positioning ring sleeve, a positioning ring protrusion, and multiple cutting blades. The positioning ring sleeve is a horizontally arranged hollow disc-shaped structure that fits over the tool and is used to contact the top surface of the steel plate. The positioning ring protrusion is located below the positioning ring sleeve and is used to contact the side of the steel plate. The multiple cutting blades are located between the positioning ring sleeve and the positioning ring protrusion, and are evenly distributed around the axial direction of the tool.

[0106] In this way, when the robotic arm moves the cutting tool close to the steel plate, the positioning ring contacts the top surface of the steel plate, and at the same time, the positioning ring protrusion moves close to the side of the steel plate, thereby achieving automatic positioning. Simultaneously, the electric spindle drives multiple blades to rotate, realizing the cutting of the steel plate edges. Since the structural form of the chamfering tool is not the focus of this embodiment, and the forming tool is common knowledge and conventional design in the art, those skilled in the art can design various types of chamfering tools according to their own needs to use with the chamfering head in this embodiment.
